Calculation of related parameters of Spur Planetary Gear System

As shown in the figure is the structural diagram of the straight gear planetary gear transmission system. The planetary carrier and sun gear are the input and output components of motion and power respectively. The inner gear ring is fixed. The three planetary gears in the system have the same design parameters and are evenly arranged on the planetary carrier.

In the picture:

Tin — input torque;

Tout — output torque;

S –sun wheel;

C — planet carrier;

P — planetary gear;

R — inner gear ring.
